One of my old summer jobs a guy would go up to women and start massaging their shoulders or backs. It does happen.
Women can touch men almost in almost any way, say almost anything - and no man dares return the treatment.
What red blooded male would turn down a woman's sexual advances unless she was hideous?
Maybe in a Summer Job environment, but this stuff would not be tolerated in a professional environment. At a minimum your supervisor would pull you aside and give you a verbal warning to knock it off. And that is the absolute minimum. Maximum, you would be terminated immediately "for cause". The sexual harassment environment has made every company a target for overt, or implied sexual harassment that can be from a glance, to a comment, to physical contact.
It's best to think of women in the workplace as nothing more than office equipment, like a copy machine. If you want to talk, chat and socialize - seek out members of your same gender. Because all it takes is one person to be in the wrong mood - and your career is over. Yes, it's extortion ... govermentally sanctioned extortion. Anything you say, have said or may have ever implied, in any time or circumstances can be brought against you without warning, or cause - at any time.
Rule of thumb - if you value your job, don't socialize with your female co-workers. If you don't care about your job, do whatever you want to do.
